.SH NAME
putdgrp \- edits device group table
.SH SYNOPSIS
.LP
.nf
\fBputdgrp\fR [\fB-d\fR] \fIdgroup\fR [\fIdevice\fR]...
.fi

.SH DESCRIPTION
.sp
.LP
\fBputdgrp\fR modifies the device group table. It performs two kinds of
modification. It can modify the table  by creating a new device group or
removing a device group. It can also change group definitions by  adding or
removing a device from the group definition.
.sp
.LP
When the command is invoked with only a \fIdgroup\fR specification, the command
adds the specified group name to the device group table if it does not already
exist. If the \fB-d\fR option is also used with only the \fIdgroup\fR
specification, the command deletes the group from the table.
.sp
.LP
When the command is invoked with both a \fIdgroup\fR and a \fIdevice\fR
specification, it adds the given device name(s) to the group definition. When
invoked with both arguments and the \fB-d\fR option, the command deletes the
device name(s) from the group definition.
.sp
.LP
When the command is invoked with both a \fIdgroup\fR and a \fIdevice\fR
specification and the device group does not exist, it creates the group and
adds the specified devices to that new group.
.SH OPTIONS
.sp
.LP
The following options are supported:
.sp
.ne 2
.na
\fB\fB-d\fR\fR
.ad
.RS 6n
Delete the group or, if used with \fIdevice\fR, delete the device  from a group
definition.

.ne 2
.na
\fB\fB3\fR\fR
.ad
.RS 5n
If executed with the  \fB-d\fR option, indicates that an entry in the device
group table for the device group  \fIdgroup\fR does not exist and so cannot be
deleted. Otherwise, indicates that the  device group \fIdgroup\fR already
exists and cannot be added.
.RE

.sp
.ne 2
.na
\fB\fB4\fR\fR
.ad
.RS 5n
If executed with the  \fB-d\fR option, indicates that the device group
\fIdgroup\fR does not have as members one or more of the specified devices.
Otherwise, indicates that the device group  \fIdgroup\fR already has one or
more of the specified devices as members.
